为全面评估我国近岸微塑料的污染现状,本文综述了我国近岸大气、陆地和海洋不同区域微塑料的采集分离、分析方法、污染分布特征及生态危害等的研究进展,并展望了我国近岸微塑料未来研究方向.研究表明,近岸大气、沉积物和海水均有微塑料的存在,相较于全球其他近岸海域,我国近岸微塑料丰度范围整体上处于中低水平.此外,微塑料及其复合污染物对我国近海生态造成一定危害.我国近岸微塑料在时空分布、源汇格局及生态风险机制方面尚不明确,建议未来在微塑料研究方法标准化的基础上,对微塑料污染进行大范围的长期监测,关注微塑料在大气-陆地-海洋之间的迁移输运,并对微塑料复合暴露的毒理机制及其对人类潜在健康风险等方面进行探索和研究,为我国海洋微塑料污染评估和治理提供参考.

●AIM:To investigate a pioneering framework for the segmentation of meibomian glands(MGs),using limited annotations to reduce the workload on ophthalmologists and enhance the efficiency of clinical diagnosis.●METHODS:Totally 203 infrared meibomian images from 138 patients with dry eye disease,accompanied by corresponding annotations,were gathered for the study.A rectified scribble-supervised gland segmentation(RSSGS)model,incorporating temporal ensemble prediction,uncertainty estimation,and a transformation equivariance constraint,was introduced to address constraints imposed by limited supervision information inherent in scribble *** viability and efficacy of the proposed model were assessed based on accuracy,intersection over union(IoU),and dice coefficient.●RESULTS:Using manual labels as the gold standard,RSSGS demonstrated outcomes with an accuracy of 93.54%,a dice coefficient of 78.02%,and an IoU of 64.18%.Notably,these performance metrics exceed the current weakly supervised state-of-the-art methods by 0.76%,2.06%,and 2.69%,***,despite achieving a substantial 80%reduction in annotation costs,it only lags behind fully annotated methods by 0.72%,1.51%,and 2.04%.●CONCLUSION:An innovative automatic segmentation model is developed for MGs in infrared eyelid images,using scribble annotation for *** model maintains an exceptionally high level of segmentation accuracy while substantially reducing training *** holds substantial utility for calculating clinical parameters,thereby greatly enhancing the diagnostic efficiency of ophthalmologists in evaluating meibomian gland dysfunction.
